Compare carbon and phenolic airframe tubing for high power rockets. Learn strength, weight, and lead time trade-offs to choose the right material for your build.
Quick Answer
Choose phenolic tubing for most high power builds where cost and lead time matter; choose carbon tubing when you need maximum strength with minimal weight for high-velocity or high-thrust flights.
Strength and Weight Trade-Off
Phenolic tubing with a fiberglass wrap offers excellent strength for nearly any flight profile, making it a versatile choice for standard high power rockets. Carbon tubing, on the other hand, is about the same weight as phenolic but stronger than glass-wrapped phenolic, giving you a higher strength-to-weight ratio for demanding applications.
If your rocket will see rough handling, hard landings, or high-stress flights, both materials can handle it, but carbon provides an extra margin of strength without adding weight. The trade-off is cost: carbon tubing is significantly more expensive, so you need to decide if that extra performance is worth the premium.
Lead Time and Customization
Both phenolic and carbon airframe tubes are made to order, so plan ahead. Phenolic tubing has a 2-4 week lead time, while carbon tubing takes 3-5 weeks. If you need custom cuts, be sure to specify them when ordering to avoid delays.
For a project with a tight deadline, the shorter lead time of phenolic might be the deciding factor. If you can wait the extra week, carbon offers superior strength for high-performance builds.
Deciding Between Carbon and Phenolic
- Flight profile: For standard high power flights, phenolic is sufficient. For high-thrust, high-velocity flights, choose carbon to handle the extra stress. Match the material to your motor and speed expectations.
- Weight budget: Both materials weigh about the same, so carbon's advantage is strength, not weight savings. If you need maximum strength without adding weight, carbon is the choice. Don't expect carbon to lighten your rocket; it strengthens it.
- Budget and lead time: Phenolic is more affordable and has a shorter lead time (2-4 weeks vs 3-5 weeks). If cost or schedule is tight, phenolic is the practical pick. Order early if you need carbon; plan for the longer wait.
Product Facts
- Pre-Glassed Phenolic Airframe Tubing: Pre-Glassed Phenolic Airframe Tubing is extremely strong and able to handle nearly any flight profile, and it arrives pre-glassed and almost ready to paint. This tubing is a reliable all-rounder for most high power rockets, saving you finishing work and handling rough flights with ease.
Pre-Glassed Phenolic Airframe Tubing - 6.0" Carbon Airframe Tubing: 6.0" Carbon Airframe Tubing has a wall thickness of 0.056" and is about the same weight as phenolic yet stronger than glass-wrapped phenolic tubing. For high-thrust or high-velocity flights where every ounce matters, carbon gives you superior strength without a weight penalty.
